GEORGE M; JACKSON, OFCHICAGO, ILLINOIS, ASS-IGNOR TO THE WESTERN CLOTHCOMPANY, 0F CHICAGG, ILLINOIS, A GQRPGRATIGN 9F ILLINOIS TWO-TON EWINDOW SHADE CLG'iI-I AFT D PROCESS OF MANUFACTURE Application filedMarch 21, 1929. Serial no. 348,758.

This invention relates to a two-tone Window shade cloth and process ofmanufacture, and has for one of its principal objects the provision ofan embossed window shade cloth which has a two-color tone effect whenviewed against light passing therethrough.

One of the important objects of this invention is to provide an embossedand trans lucent window shade cloth having a vari= colored patternbrought into relief by havembossed lines whereby a practically infinitevariety of patterns and color combinations may be produced.

Other and further important objects of the invent-ion will be apparentfrom the disclosures in the accompanying drawings and followingspecification.

The invention, in a preferred form, is illustrated in the drawings andhereinafter more fully described.

In the drawings:

Figure 1 is a plan view of a piece of embossed window shade cloth havinga color pattern of various tone efiects.

Figure 2 is a sectional view taken along any representative line ofFigure 1.

Figure 3 is a diagrammatic view illustratingthe preferred process ofmanufacture of this improved shade cloth.

As shown in the drawings:

The reference numeral 10 indicates generally portion of a sheet ofwindow shade cl l formed of the usual materials, namely ton cloth or thelike, having applied thereto a plurality of coats of iller or size whichfor he purpose of this invention is of a composition so as to render thecloth pliable to a certain degree,-and accordingly able-to receive andretain impressions from an embossa ing roll or the like. Thiscomposition may also be of suchmaterial as to render the shade clothitself waterproof, and accordingly washable. i

T 1e cloth after having been preliminarily coated or filled isembossed'in any usual or convenient manner by passing through embossingrollers, the design or pattern including score lines set at variousangles to the edge of the cloth as illustrated at 12, 14, and 16 inFigure 1. v,

The coatin or filling applied to the cloth before processing ispreferably of a white or neutral color, andafter the embossinghas beenaccomplished, the cloth is given a final coating of any desired color,this coating material being illustrated at 18 in Figure 8, the

cloth at the time being passed over a table or the like 20 by means offeed rollers 22, and with its surface in contact with the lower edge ofa doctor knife or the like 24. This doctor knife allows only thin layerof color coating-to be applied to the cloth, and it will evident from aninspection of'the figure that .the highest parts 26 of the embossedpatterns will receive little or no coloring material. Those scores orshade lines 12 perpendicular to the edge of the doctor knife. will,however, receive considerable of the coating materiahwhile thosescoreslG at an angle to the blade of the knifewill receive lesslinproportion to their angularity, while those scores 14' which areparallel to the edge of the blade 24; will receive merely a slightdeposit ofthe coating material 18. I

The shade itself being translucent will allow the passage of lighttherethrough even though thecoating material 18 has been applied, and asthis is of varying degrees of thickness in its deposits upon thecloth,it will be evident that varying amounts of light will pass throughthe cloth when the same is in position against a window or the like. 1Ac cordingly, a very attractive and delightful two-tone or morecolorelfect is produced, the same being outlined by the patternsthemselves, thereby resultin in a very novel, dec-. orative, and usefularticle. a i I am aware tha't ,many'chang'es may be made and numerousdetails of construction varied throughout a wide range withoutdepartingfrom the principles of this invention, and I therefore do not proposelimiting the patent granted hereon otherwise than as necessitated by theprior art.

I claim as my invention:

1. A two-tone Window shade cloth having a patternformed by embossedlines, and a colored coating of varying degrees of thickness in the saidembossed lines, the angle of the lines with respect to the edge of thecloth determining the amount of coloring material.

2. Avaricolored window shadecloth having patterns formed of linesindented into the material-of the cloth, certain of said lines beingindented deeper than others and forming the main pattern outlines, andcertain other of said lines comprising groups of parallel groovesarranged at different angles with respect to each other and with respectto the edge of the cloth.

3. A varicolored windowshade cloth having patterns formed of ii nesindentedinto the material of the cloth, certain of said lines beingindented deeper than others and forming the main pattern outlines, andcertain other of said lines comprising groups of parallel groovesarranged at dilferent angles with respect to each other and with respectto the edge of the cloth, and a colored coating in the indentations. i

4, A varicolored window shade cloth having patterns formed of linesindented into the material of the cloth, certain of said lines beingindented deeper than others and forming the main pattern outlines, andcertain other of said lines comprising groups of parallel groovesarranged at different angles with respect to each other and with respectto the edge of the cloth, and a colored coating applied to saidindentations, the depth of said indentations determining the relativedeposit of coloring material;

5.- A varicoloredwindow shade clothhaving patterns formed of linesindented into the material ofthe clot-h, certain of said lines beingindented deeper than others and forming the main pattern outlines, andcertain other of said lines comprising groups of parallel groovesarranged at different angles with respect to each other and with respectto the edge of the cloth, and a colored coating ap plied to saidindentations, those indentations parallel to the edgeof the cloth havinga greater quantity of coating material.

,6. A process of manufacturing two-tone window shade cloth including theprelimi nary application, of a relatively flexible neutral-coloredtranslucent coating to a cloth base, embossing the coated cloth, and thelater application of a colored coating to the embossed cloth. I
